When making design with bridge configuration, bridge deck overlay which was only treated as the appendant of bridge, currently not make special calculate and analyze about it, at the same time, current codes also just give directed account for method、material and thickness of deck pavements, there havent any design theory and index to dependent, so it is necessary to do some systemic study about concrete bridge deck overlay and make certain about the stress and distortion characteristic of the deck pavements.

桥面铺装作为特殊的路面结构，它起着保护桥梁和承担路面功能的作用。但是目前，在进行桥梁结构设计时，桥面铺装层只是作为桥梁工程的附属结构，一般不作专门的计算分析，现行规范也只是对桥面铺装的做法、材料、厚度做了指导性的说明，至今没有可以依据的设计理论和指标，因此有必要对桥面铺装展开系统的研究，明确铺装层结构的受力和变形特点。

The results show that, with the same steel consumption, the longitudinal and transverse girder deck scheme is a little better in stiffness, dynamic characteristics and stability than those of the other scheme's. For the dense transverse girder deck scheme, because of no longitudinal beams, the axial forces of the tie beam and the deck slab are higher than those of the other scheme's. The improving rate of the axial force for the deck slab is about 50%. The inside and outside bending moments of the cross beams reduce to below half of the other scheme's. The longitudinal stress of the deck slab is higher on the whole and the traverse stress is less than that of the other scheme's. The maximum traverse stress of the deck slab is below 40% of the other scheme's.

研究结果表明：在材料用量相同时，纵横梁方案桥梁刚度较密布横梁方案的桥梁刚度稍大，桥梁动力特性比后者的优，其稳定性也比后者的强；对于密布横梁方案，由于不设纵梁，系梁和混凝土板承受的纵向力都较纵横梁方案的大，混凝土板增幅达50%左右，横梁面内和面外弯矩则明显减小，都低于纵横梁方案的一半，混凝土板顺桥向应力整体比纵横梁方案的高，而横桥向应力则较低，最大值低于纵横梁方案的40%。

The ratio of the vertical load distributed between the arch rib and the tie beam of the two schemes is the same. For the integral girder deck scheme, the longitudinal beams and the deck slab of endure more axial force compared to the ballast girder deck scheme, especially to the deck slab with a conspicuous increase of the axial force and higher stress, and the tie beam endure less. The force-bearing characteristics of the cross beams under the integral girder deck scheme is obviously better than that of the ballast girder deck scheme, especially at the two ends of each cross beam.

在受力上，与道碴板桥面方案相比，整体桥面方案竖向荷载在拱肋和系梁之间的分配基本相同，混凝土板和纵梁分担的纵向力则相对更大，尤其是混凝土板，增幅较明显，应力水平整体较高，系梁分担的纵向力则得到减小，横梁的受力状况整体桥面方案明显优于道碴板桥面方案，特别是在梁端处。

First, this paper presents three girders model with double cable planes which main girder and side girder is connected by rigid arms, analyzes the dynamic characteristic of Yonghe cable-stayed bridge and obtains its natural vibration modes (i.e., frequency, damping values and the mode shapes ) by ANLSIS structural analysis program and uses these parameters as dynamic dactylogram of the intact case of cable-stayed bridge. Using the passage of random as the ambient vibration ,the dynamic properties of Yonghe Bridge is measured and the modal parameter of its 15 years after is identified and used as dynamic dactylogram of the damaged case. By the finite element analysis and locale vibration test, damaged and undamaged modal parameter is analyzed and curvature mode shape, which is sensitive to damage state, is introduced as possible candidate for identifying and locating damage in the cable-stayed bridge. Selecting the branch of part measured point from modal parameter, this paper deduces the damaged index which can detect the possible damaged location of the cable-stayed bridge deck and identifies the damaged region and degree for Yonghe Bridge. For the purpose of structural condition monitoring in in-situ , from another viewpoint, this paper introduces the method called the best optimization vector to detect damaged location and degree. The accuracy and reliability of the method presented in this paper are demonstrated by static analysis and test and the healthy state of Yonghe Bridge can be evaluated.

First, the actuality of Jiangyin bridge's deck surfacing are reviewed. Improper materials and pavement structures, severe conditions, overload and heavy traffic are deemed to be the main factors which result to deterioration of the deck surfacing. Then, programme of local repair asphalt mixture design has been proposed. It is considered that epoxy asphalt mixture and guss asphalt mixture are propitious to the local repair. The epoxy asphalt is also chosen as the adhesive layer material. Next, two pavement structures for steel deck plate surfacing have been tested. The most suitable asphalt surfacing structures have been proposed for the local repair. Finally, the elaborate local repair schemes of Jiangyin bridge's deck surfacing are proposed.

Lo Wu Bridge is not only a narrow bridge at the time, only moving train, but no bridge unroofed shed, left to sun and rain. In 1959, the government will be the Lo Wu Bridge turned into steel and concrete bridge deck has also widened more than doubled. 1962, also stamped with an iron Peng Ding, added in the iron bridge on both sides of the iron railing, and covered the sidewalk. The 20th century, the early 70s, the author in Guangzhou Railway Administration to do secretarial work, on several occasions to the Footbridge is the first walk.

当时的罗湖桥不但桥面狭窄，只能行驶火车，而且桥身无顶无棚，任凭雨淋日晒。1959年，人民政府将罗湖桥改建成钢筋水泥桥，桥面也加宽了一倍多。1962年又加盖了铁皮篷顶，在铁桥两侧增设了铁栏杆，并铺上了人行道。20世纪70年代初，笔者在广州铁路局做秘书工作，曾多次到罗湖桥头漫步。
